Kant posits the “thing-in-itself” as the ontological foundation underlying the existence of phenomena. However, his framework lacks the necessary metaphysical intermediaries to explain how this foundation can be “empty,” yet possess “spirit,” and serve as the basis for all phenomena. Marx’s notion of objective relationships provides insight into the existence of universal and necessary media that bridge ontology and phenomena, transcending their differences. Whitehead’s organic cosmology further advances this idea by integrating cosmology with the mesocosm, achieving a comprehensive construct of ontology. The ancient Chinese concept of “Tao” closely aligns with Kant’s “thing-in-itself,” and the “integration of Tao and Qi” parallels Whitehead’s approach to perfecting ontology. Moreover, the Chinese theory of the “two phases of gas and matter” resonates with the concept of “wave-particle duality,” creating a harmonious and unified ontological structure. This complete and harmonious ontology lays a philosophical foundation for the construct of “world aesthetics.”
